Abstract: Data de-duplication is the important data compression techniques which is used in eliminating the duplicate copies of repeating data in the cloud storage environment, and has been widely used in cloud storage environment to reduce the amount of storage space needed and used to save bandwidth. The convergent encryption technique has been used to encrypt the data before outsourcing, it is used protect the confidentiality of the data which is sensitive in nature while supporting de-duplication. Authorized data de-duplication has been introduced to better protect data security. This proposed system is different from the traditional de-duplication systems, the differential privileges of the users are further considered while processing duplicate check besides the data itself. Presented several new de-duplication constructions supporting authorized duplicate check in a hybrid cloud architecture. Security analysis proves that this scheme is secure in terms of the definitions specified in the proposed security model. Implementation of prototype for the proposed authorized duplicate check scheme has been done and also conducted the testbed experiments using this prototype. Compared to the normal operation the proposed authorized duplicate check scheme incurs minimum overhead.
Keywords: De-duplication, authorized duplicate check, confidentiality, hybrid cloud.
